I declined my oath ceremony scheduled for Sept 15 2021 because my grandmother was in the hospital. It is now March 6, 2022 and I still haven't been rescheduled.

The state department website is one riddled with bluster and no bite.  
 
You only have to use a USA passport to leave the USA when using an aircraft.  As anyone who travels by cruise ship knows, USA citizens routinely and without issue use a USA birth certificate to leave and  enter the USA each day in a cruise ship by the hundreds if not thousands.  
 
You use your USA passport when you check in for your flight.  There are no penalties if USA citizens don’t present their USA passport to the airline.  It’s just against a law that has no penalties.  This law is broken by people with multiple citizenships each day, both exit and entrance.  However some times CBP does staff airline jetways and there if a USA citizen doesn’t have a USA passport, I presume the citizen would be denied boarding.  
 
If you happen to have multiple citizenships, and another passport gives you an advantage over your USA passport to enter the country, such as giving you a visa waiver, then you also present your other passport.  
 
The airlines send manifests to CBP for each exiting flight and thus CBP knows which passengers are USA citizens that used their USA passport.  
 
When I travel to Canada, I present my USA passport at check in.  When I land in Canada, I present my Canadian passport to the immigration officer so that I my stay is not recorded as limited to 6 months.  
 
On return I just present my USA passport to the airline, and then 5 minutes later to CBP at the preclearance desk.  
 
If Canada had formal exit controls like the Schengen Area then I would present both passports to the airline, my Canadian passport to CBSA, and my USA passport to CBP.  

This is correct, it wouldn’t be an issue when changing your name to take on spouse’s last name. All you will need is proof of citizenship and marriage certificate. My wife and I married in 2015 and she didn’t change her last name until 2019. 
 
Like everyone said, get your passport first along with a passport card. Then use the passport to change your name with social security. 
 
The social security card may be a longer process. If you have an issue with a social security agent being adamant with whatever script they’re reading from, I might even suggest going through the process of changing your name first because of marriage. And then go through the process of changing citizenship status after that. 

Also, register to vote. Midterms are coming up.

It won't be an issue, taking a spouses last name does not require an actual court/judge to do it. Since all she wanted to do was assume her husband's name she just shows her marriage certificate as her proof of name change. It's just cheaper to wait until  ROC or Naturalization to change it during the process. Most don't realize the name change can happen at ROC and wait until Naturalization.
 
Even if nothing comes in the mail your marriage certificate is your legal document to take on your husbands last name. You will submit that when you apply for the passport. 

Congratulations!  Personally, I would first get a passport moving, then you can work on changing your name on your SSC and DL.  
 
 

Best way to update SS card is make an appointment with nearest office and go there to fill out the Form SS 5
it can be done by mail but most of us hate to mail out important documents 
 
DL not as important to change immediately but check 
Colorado DL site 

Much to my surprise, what you said is absolutely correct my second marriage certificate. Great tip!

Yes, I do *have* one....I can't find it. I think I left in accidently in Canada.
 
However, if anyone else is in this situation, the date of your last divorce is written on your next marriage's marriage certificate.

Assuming you are Canadian, then enter Canada / Mexico over land with your Canadian passport, return to the USA with a photocopy of your USA naturalization certificate (since the original will  be with the USA passport agency).  
 
Be ready for a long stay in CBP secondary inspection.  However your right to enter the USA as a U.S. citizen is absolute, https://en.m.wikipedia.org/wiki/United_States_passport
 
In Nguyen v. INS, the Supreme Court stated that U.S. citizens are entitled "...to the absolute right to enter its borders."[53]Lower federal courts went as far as to declare that "...the Government cannot say to its citizen, standing beyond its border, that his reentry into the land of his allegiance is a criminal offense; and this we conclude is a sound principle whether or not the citizen has a passport, and however wrongful may have been his conduct in effecting his departure."[54] Therefore, even in the absence of a valid passport, U.S. citizens are not denied entry into the United States, though these travelers may be delayed while the CBP attempts to verify their identity and citizenship status.[55]
 
Do apply for a passport card too.  

If you are able to drive to Aurora and can get a same day appointment at the Passport Agency there for Urgent travel, it might be a better option than trying to expedite through the mail.  Here is the information to contact them as well as the Passport Agency in Aurora.  I don't see the need to have a purchased airline ticket to make an appointment for urgent travel.
 
Good Luck!

If you were eligible for naturalization based on being an LPR for 5 years then this simplifies the case.  
 
You can hire a lawyer to move your case into federal court where a judge will take your oath. 

I mean, for sure COVID didn't help, but to use that excuse and sit on simple cases for two years is total BS. Somebody posted an article about cases being stuck in an office that -supposedly- nobody has access to. Mind blogging that just because a simple door can't be unlocked, families are kept separate. Yet as @iwannaplay54has rightfully said, credit cards are charged at light speed. They don't seem to be understaffed in the "charging" department!

They finally answered my out of normal processing inquiry:
 
It could take up to 90 days to schedule your oath ceremony.
 
LOLOLOLOL What a joke.

I see you are in Colorado.  Before abandoning your application contact Senator Bennet, they were able to find out why my case was stuck. 
23 months is too long to wait!

Thank you! No one has told me how to do this before. Much appreciated.
